ASH-REMOVER FOR BOILERS.-

SPECIFICATION forming part of Letters Patent No. 676,930, dated J u'ne 25, 190 1.

Application filed February 25,1901- Serial No.48,850. (No model.)

To all whom it may concern: To the outer face of the opposite wall 14 of Be it known that we, ELIJAH FLEET WEEs, the ash-pit is hinged a chute comprising side residing at Point Pleasant, in the county of pieces 20 and 21, having their forward ends Mason and State of West Virginia, and WIL- curved at the upper portions, and which side 55 5 LIAM HARRY MARTIN, residing at Gallipolis, plates are continued downwardly at their forin the county of Gallia and State of Ohio, citiward ends and have a cross-bar 23 attached zens of the United States, have invented a to the rear faces thereof to brace the plates,- new and useful Ash-Remover for Boilers, of this downwardly-projecting portion. forming which the following is a specification. a discharge-spout. The top of the chute is 60 This invention relates to ash-removers for formed by a plate 24, which is disposed upon boilers; and it has for one object to provide a and is bent to conform to the upper and end construction particularly adapted for marine edges of the side plates. The side plates of the boilers, although it is well adapted for stachute have upwardly-projecting cars 25 and tionary boilers, and wherein the ashes will 26, which are pivoted to ears 27 upon the wall 65 be conveyed laterally of the ash-pit and carof the ash-pit, and projecting outwardly from ried through the side of the ash-pit and dethe wallet the pit, above the opening 16 and posited through a suitable chute, another objust below the upper plate of the chute, is a ject of the invention being to provide a simguard-plate28,which prevents ash fromaccess ple and efficient construction with which the to the interspace between the end of the top 70 2o ashes may be quickly removed continuously plate and the wall of the pit and which would or intermittently and wherein the chute may likely prevent efficient pivotal movement of be moved into and out of its discharging pothe chute.

Perforations 33 are pit 13, into which the ashes from the furnace formed in the plates of the belt adjacent to fall in the usual manner. In the side Walls the ends thereof, and these perforations re- 14: and 15 of the ash-pit are formed openings ceive pins 3s upon the faces of the drums to 17 and 18, and adjacent to the opening 18 and insure movement of the beltby rotation of a 10c exteriorly of the ash-pit is a hexagonal drum drum.

19 for a purpose to be presently explained. The drum 19 is the belt-driving drum and is provided with a gear 35, with which engages a gear 36 on the shaft 37 of a steamengine 38, which may be fed from the boilers 10 and 11. As this engine operates it rotates the drum l9 and the belt is fed with its upper side in the direction of the chute, so that the ashes that drop onto the belt are conveyed laterally and deposited into the spout. In the presentinstance the spout is shown positioned to discharge through an opening 37, which may be an opening in the deck of the stokehole o'fa vessel or may open into a pit, if the boilers be stationary.

The walls of the ash-pit are provided with slanting shoulders 40 and 41, of which the shoulder 41 projects over and close to the upper side of the conveyer-belt, while upon the shoulder 40 is pivoted a plate which projects over and close to the belt, so that the ash that may not drop directly upon the belt may readilyslidethereonto'. By pivotingtheplate it may be raised to permit of application and removal of the parts therebelow.

It will be noted that while the upper side of the belt runs through the ash-pit the lower side thereof runs through a passage beneath the bottom of the ash-pit and the deck of the vessel or other support for the furnace and that the upper side of the belt is permitted to sag. The object of the arrangement is to permit of the'upper side of the belt that receives and conveys the ashes to move through the water that lies at all times in the bottom of the pit, and so extinguish the cinders.

While in the present instance but'two boilers are shown, it will be understood that the apparatus may be used in connection with a battery of any number of boilers.

What is claimed is- 1. The combination with a furnace having an ash-pit having openings in its side Walls and adapted to hold water in the bottom portion thereof below said openings, of supportthe pit, the lower side of the belt being returned below the pit and the upper side of the belt being unsupported between the sides of the pit to permit it to sag into the water in the pit.

2. The combination with a furnace having an ash-pit provided with openings in its side walls, of a chute hinged adjacent to an open ing, a supporting-drum mounted in the chute, a supporting-drum disposed exteriorly of the pit and adjacent to the opposite opening, and a conveyer-belt passed through. the openings and transversely through the pit and engaged with the drums.

3. The combination with a furnace having an ash-pit provided with openings in its side walls of a chute hinged adjacent to an opening for movement into and out of operative relation to said opening to receive therefrom, a drum mounted in the chute, a second drum mounted adjacent to the opposite opening and exterior to the pit, a belt engaged with the drums, a plate disposed transversely of the chute and adjacent to the under face of the top side of the belt, and means engaged with one of the drums for feeding the belt.

4. The combination with a boiler having an ash-pit provided with openings in its opposite sides and adapted to hold water in the bottom portion thereof below said openings, a conveyer-belt passed through the openings and transversely through the pit, supportingdrums for the belt, a shoulder in the pit pro jecting over an edge of the belt to deflect ashes thereto, and a hinged plate disposed to project over the opposite edge of the belt to deflect ashes thereto, the belt being unsupported between the sides of the pit to permit it to sag into the water in the pit and being returned below the pit.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
